Esperanto Affixes: How mal-, -in-, -ej- and Friends Multiply Your Vocabulary

You have already met and in this course, and you probably learned them as two more words on a list. They are not. They are and with a piece bolted on, and once you see the mechanism you get several hundred words you were never taught.

- reverses everything

The most useful morpheme in the language. Put - on the front and the meaning flips to its exact opposite:

Root you knowWith -Meaning
, goodbonabad
, biggrandasmall
, newnovaold
, strongfortaweak
, fastrapidaslow
, longlongashort
, to loveamito hate
, to helphelpito hinder

Look at the English column. Good and bad, big and small, love and hate share nothing. Every antonym pair in English is two unrelated words and costs a learner two slots.

In Esperanto every pair costs one root plus a prefix you learn once. That table alone is eight free words from this course's own vocabulary, and there was nothing new in it.

-in- makes it female

is father. is mother. You already know both, and you already know the suffix without having been told:

RootWith -in-Meaning
, manvirinowoman
, fatherpatrinomother
, sirsinjorinomadam
, kingreĝinoqueen

Four words in this course, and only two roots' worth of effort. The suffix goes before the -o, because the -o is still doing its usual job of marking the noun.

And - on the front takes both sexes together, which English can only do with an entirely different word:

patro + patrino = patroj, parents

viro + virino = viroj, men and women

The place, the person, the repeat

Three more that carry a lot of traffic.

-- is the place where something happens:

  • (to learn) gives , a school
  • (to work) gives o, a workplace
  • (to reside) gives , a dwelling

-- is the person who does it professionally:

  • (to teach) gives , a teacher
  • gives o, a worker
  • gives , an Esperanto speaker

- is again, or back:

  • (to come) gives , to come back
  • (to give) gives i, to give back
  • (to see) gives , to see again

is in this course at rank 200. You now know it costs nothing beyond .

-- and --: the volume knob

A matched pair that scales the root down or up:

Root-- smaller-- bigger
, house, cottageo, mansion
, looki, glancei, stare
, biga, biggish, enormous
, lovelya, pretty, gorgeous

English reaches for a different word each time: house, cottage, mansion. Esperanto turns a dial.

This is why 200 roots is not 200 words

Take one root from this course, , and apply what you now know:

(good), bono (goodness), bone (well), boni (to be good), (bad), e (badly), (excellent), a (decent), plibonigi (to improve), o (a villain).

Ten words. One root, plus endings and affixes that work identically on every other root you hold.

This is the honest form of the claim that Esperanto is faster to learn. It is not that the words are easier to pronounce or that the grammar is short, though both are true. It is that vocabulary in Esperanto compounds, because the derivational system is regular and productive and nobody has to approve a new combination.

What to take away

Learn these seven and every root you own multiplies:

AffixJobExample
-exact opposite, small
-in-female, mother
-both sexes together, parents
-again, back, to come back
--the place for it, school
--the person who does it, teacher
-- / --smaller / bigger / o

Then read the table of - words again and notice that you can now say bad, small, old, weak, slow, short, hate and hinder, none of which appear anywhere in this course.

Frequently asked questions

What does mal- mean in Esperanto?
It reverses the meaning of the root completely. Bona is good and malbona is bad; granda is big and malgranda is small; ami is to love and malami is to hate. It is the single most useful affix in the language, because it halves the adjectives you need to learn - every antonym pair in English costs two unrelated words, and in Esperanto it costs one root and a prefix you already know.
Is patrino a separate word from patro?
No, and that is the point. Patro is father and the suffix -in- makes it female, so patrino is mother. The same suffix gives you virino from viro (man to woman), sinjorino from sinjoro (sir to madam), and reĝino from reĝo (king to queen). Three of those four are in this course already, and you learned them as vocabulary before you knew they were built.
Can I invent Esperanto words with affixes?
Yes, and doing so is normal rather than clever. The affixes are productive, which means they attach to any root where the sense holds, and a fluent speaker will understand a combination they have never heard because the pieces are unambiguous. If you know lerni (to learn), then lernejo (school, the place for learning) and lernanto (a learner) are available to you without permission from a dictionary.
Which Esperanto affixes should a beginner learn first?
mal- (opposite), -in- (female), -ej- (place), -ist- (person who does it), re- (again) and the pair -et- / -eg- (smaller / bigger). Those seven cover the overwhelming majority of affixed words you will meet in your first year, and each one multiplies every root you already hold rather than adding a single word.
